"All education is self-education. Period. It doesn’t matter if you’re sitting in a college classroom or a coffee shop. We don’t learn anything we don’t want to learn.

Those people who take the time and initiative to pursue knowledge on their own are the only ones who earn a real education in this world.

Take a look at any widely acclaimed scholar, entrepreneur or historical figure you can think of. Formal education or not, you’ll find that he or she is a product of continuous self-education.

If you’re interested in learning something new, this article is for you. Broken down by subject and/or category, here are several top-notch self-education resources I have bookmarked online over the past few years.

Note that some of the sources overlap between various subjects of education. Therefore, each has been placed under a specific subject based on the majority focus of the source’s content."
